On November 7th 2011, i held a TEDx Talk at TEDx Delft, one hour after launching a near space high altitude balloon. Everything i have about that is written below.
We launched the balloon, we had a connection up to 15km for 45minutes, received 32 images before the processor blew. We found it back a few hours later in Rotterdam.

Adventure of the payload
How we got it back
Soundfragment comes here
Immediatelly when it landed, a woman got it. It landed 20 meters from the river Maas in Rotterdam. She tried to call us (i didnt pick up, i was attending a TEDx Delft talk, she thought it was a bomb, so “She opened it ” (=ripped the whole front off). Then she called the police, which said “Oh yeah we know about that, it’s not a bomb”, then i called her, picked it up after a 15minute drive!

Hi Tim,
Would be glad to help out on the 7th if you need any ground crew assistance. Let me know.
Cheers

It would be great if you can be at the Aerospace faculty around 13:00 would be good i think. That way we have plenty of time to set up base.
